Insomnia, a disorder of sleep, occurs occasionally in most people but usually lasts only a few days. The body then "corrects" itself naturally, and people return to a normal pattern of sleep. Insomnia may be short-term (less than three weeks) or chronic, lasting longer than three weeks. Contributing factors include, but are not limited to, poor sleeping habits, stress, jet lag, medications, disease, and depression. Chronic insomnia may warrant the use of sedative/hypnotics medications; however, it is important that the treating physician perform a complete diagnostic evaluation as well as take medication and substance abuse histories, to exclude secondary insomnia due to other conditions.

Practitioners should give the following information and instructions to patients receiving barbiturates.
There have been reports of people getting out of bed after taking a sedative-hypnotic and driving their cars while not fully awake, often with no memory of the event. If a patient experiences such an episode, it should be reported to his or her doctor immediately, since “sleep driving” can be dangerous. This behavior is more likely to occur when sedative-hypnotics are taken with alcohol or other central nervous depressants (see WARNINGS). Other complex behaviors (e.g. preparing and eating food, making phone calls, or having sex) have been reported in patients who are not fully awake after taking a sedative-hypnotic. As with sleep-driving, patients usually do not remember these events.
The use of barbiturates carries with it an associated risk of psychological and/or physical dependence. The patient should be warned against increasing the dose of the drug without consulting a physician.
Barbiturates may impair mental and/or physical abilities required for the performance of potentially hazardous tasks, such as driving or operating machinery.
Alcohol should not be consumed while taking barbiturates. Concurrent use of the barbiturates with other CNS depressants, including other sedatives or hypnotics, alcohol, narcotics, tranquilizers, and antihistamines, may result in additional CNS depressant effects.
